Inguinal Canal & Spermatic Cord- Exam III Flashcards
Strong tube that carriers sperm cells
Ductus deferens
Blood supply that carries arterial blood to the testes
Testicular artery
Plexus of veins that drains the testes; starts out as mesh of interconnected multiple veins that will merge together ultimately on either side of the body called the testicular vein
Pampiniform plexus
Branch of lumbar sacral plexus that is sexually dimorphic
Genitorfemoral nerve
In males the genitorfemoral nerve carries _____ & _____.
In females the Genitofemoral nerve carries:
Somatic sensory & somatic motor
Somatic sensory only
The somatic motor function of the Genitofemoral nerve is responsible for the innervation of what muscle:
Cremaster muslce
List the 6 components of the spermatic cord:
- Ductus deferens
- Testicular artery
- Pampiniform plexus
- Genitofemoral nerve
- Autonomic nerves
- Lymphatics
Location of where spermatic cord passes through body wall:
Inguinal canal
Location where sperm is manufactured:
Testes
Location in which sperm matures:
Epididymis
Type of fascia that is only found anteriorly on the abdominal wall
Scarpa’s fascia
Serous lining of entire abdominopelvic cavity:
Parietal peritoneum
If the embryo becomes a male, the dermis attached to the gubernaculum will end up at:
Bottom of scrotum
If the embryo becomes a female, the dermis attached to the gubernaculum will correspond to:
Labia majora
Male gonad:
Female gonad:
Testes; ovary
Location in which gonads originate embryonically:
Upper lumbar region around L1
What process does the gubernaculum assist in:
Migration of gonads to adult position
How does the gubernaculum move the gonads:
By shortening
The location where the gubernaculum pierces through all of the abdominal wall layers will ultimately end up forming the:
Inguinal canal
Testes will start in the plane between:
Parietal peritoneum & transversalis fascia
What is the deepest abdominal wall layer that the testes must pass through:
Transversalis fascia
What is established before the testes begin migrating?
Blood, nerve, & lymphatic supply
Where are the spermatic cord contents in relation to the tests when the testes are migrating?
Trailing behind the testes
Why can’t the testes pass through the inguinal hole? Can gubernaculum pass through?
Testes are too large; and yes gubernaculum passes with EASE BITCH
